摘要：

Dipole approximations are used to model up to three superparamagnetic particle systems as they assemble on magnetic island templates. It is shown that small variations in the ratio of particle-to-island diameter as well as the particle positions above the island can change magnetic forces from attractive to repulsive. This observation could potentially permit a template to be designed to promote single particle coverage of individual magnetic islands. (C) 2002 American Institute of Physics.
